7. What's the material of JH3?

The JH3 is choosing- aluminum alloy as the construction material- this aluminum alloy is carefully shaped with a 5-axis CNC machine, carefully hand polished, and goes through many other manufacturing processes used on high-end products to give it a pristine mirror-like finish, each “stripe” of light and shadow clearly showcased. Finally, PVD coating is also applied to the surface of the JH3 which not only increases the rigidity of the IEMs, but also allows that mirror-like finish and stripes to further shine and last longer against wear and tear.
